Questions & Answers

Can you connect two or three of these together to get a longer reach?

Can you connect two or three of these together to get a longer reach?
Asked by: allegiance
Yes, you can. I have used more than that connected together. I recommend periodically checking the set screws to ensure they remain tightened as on a couple of rare occasions they became loose over time. Overall, this product worked well for me.

how do you open the packaging on the 3/8 extension?

Asked by: DG
I used a pocket knife personally. I cut away at the plastic the bit will eventually break loose. However a pair of diagonal side cutting pliers would be a safer bet.

Does this bit extender feature dual set screws oriented 180 degrees apart?

Does this bit extender feature dual set screws oriented 180 degrees apart? I would like to see the bit tightened securely along its central axis (to reduce wobble)?
Asked by: BadMon
One set screw. For hex shaped bit shank, aka hole saw shank.

Would this work with a 4" round diamond core bit for going through masonry?

Would this work as an extension for a 4" round diamond core bit? It would allow me to core out 12" of brick and the 6" of cinder block in front of it....
